Description
Technical field
The present invention relates to the fax through internet technology, relate in particular on network, the fax control method of reliability of automatic raising.
Background technology
Along with the high speed development of internet, the NGN networking is progressively replacing the PSTN original system.Therefore the facsimile service of IP based network is used widely, and will progressively replace traditional fax services.The facsimile art of present IP based network can be divided into following two kinds according to used fax code encoding/decoding mode:
One, voice transparent transmission mode abbreviates VBD (voice band data) mode as.Promptly after detecting the facsimile signal sound incident, the gateway that links to each other with facsimile machine reports soft switch (or media controller), by soft switch (or media controller) transmitting order to lower levels, voice encoding and decoding mode is switched to G.711 mode, finish the transparent transmission of T30 facsimile signal, and then realize fax through internet.Under this fax mode, need some parameters of concrete configuration, such as G.711A or code encoding/decoding mode G.711U select; The packing of encoding and decoding speech at interval; What echo was suppressed opens or closes; The selection of voice packing redundancy etc.
Two, code encoding/decoding mode T.38.Promptly after detecting the facsimile signal sound incident, the gateway that links to each other with facsimile machine reports soft switch (or media controller), by soft switch (or media controller) transmitting order to lower levels, voice encoding and decoding mode is switched to T.38 mode, realize the encoding and decoding and the transmission of facsimile signal, and then realize fax through internet.T.38 also there are some parameters to need configuration, such as the redundancy of facsimile data and control messages, fax-rate restriction etc.
Above-mentioned two kinds of fax modes all have the shortcoming of oneself.Adopt the VBD mode, the packet loss of network and time delay are easy to cause the distortion and the time-delay of signal, so that fax failure; And adopt T.38 mode since the T.38 standard that each equipment supplier realizes there is some difference, and the workflow of different model facsimile machine and signal generation order are different, cause T.38 compatibility existing problems of mode and then fax failure.
In addition, there are VBD and dual mode T.38, in actual application,, need between dual mode, switch owing to the variation of situation because Fax over IP transmits.And at VBD with T.38 under two kinds of fax modes, all need some parameters of concrete configuration, packing interval such as encoding and decoding speech, selection such as 10 milliseconds or 20 milliseconds, the selection that voice packings is redundant, these parameters need to revise in certain network environment, and 2 times of voice redundancies are carried out in suggestion when packet loss is arranged, if network condition is good, 10 milliseconds packing interval is selected in suggestion.T.38 also have some parameters to need configuration, such as the redundancy of facsimile data and control messages, fax-rate restriction etc., these parameters also need dispose under real network is faxed environment accordingly.
The configuration of all above-mentioned fax modes and concrete parameter all is provided with revising by the on-the-spot manual configuration of equipment operation attendant at present.When the fax problem appears in the scene, need the attendant to go trace analysis to search concrete reason, after the modification configuration, fax could success.The selection of fax mode and parameter may be with the variation of network condition and telefax machine model in addition, generation dynamic change as a result causes faxing, the user attendant then reanalyses again and disposes, operation attendant workload is very big like this, along with rolling up of fax user, maintenance difficulties is increasing.
Summary of the invention
